Over the last 30 years, many environmental changes, such as those in land use and climate, have impacted on populations of birds across Europe. For effective conservation and informed decision making, we need the most up-to-date information on these impacts.

Knowing where birds occur, and how this has changed, is a crucial part in targeting conservation action, and will tell us much about the state of the wider environment. It also provides valuable data for scientific analyses, and for assessing if and how projected changes are materialising.

New opportunities have arisen, improving our ability to incorporate even the most remote parts of Europe and provide a robust baseline for future monitoring across the whole continent.

The aims of the EBBA2 project are:

• To document breeding evidence for all bird species at a resolution of 50x50 km
• To estimate abundance for all bird species at a resolution of 50x50 km
• To determine the changes in bird species distribution at a resolution of 50x50 km since the 1980s.
• To model fine-grained distribution for as many bird species as possible and project it at a resolution of 10x10 km.

The EBBA2 methodology proposed by EBCC is simple and standardized, and has been adapted for use with the Greek Grid system, which includes more than 160 50x50km squares and at least 2,000 10x10km squares!
